Title (EN) DEVICE AND METHOD FOR FIXING THE END OF AN OPTICAL FIBRE
(FR) DISPOSITIF ET METHODE DE FIXATION DE L"EXTREMITE D"UNE FIBRE OPTIQUE
Abstract:
(EN) An optical fibre (14) is optically coupled to an optically active element (13), for example a light source. In order to achieve optimum coupling, the end portion of the fibre (14) is carefully adjusted in relation to said element (13) in three dimensions. The end of the fibre is provided with a sleeve (15) slidably mounted in a bushing (17). The bushing is provided with a flange (18) which is adjustably pressed against a surface (12) on a mounting base (11) which is perpendicular to the axis of the sleeve (15). The mounting base (11) also carries the optically active element (13) near the end of the fibre (14). After the sleeve (15) and the bushing (17) respectively are adjusted so that maximum coupling is obtained between the fibre and the optical element the sleeve (15), bushing (17) and mounting base (11) are fixed together by introducing a highly fluid, quick-setting glue, preferably a cyanoacrylate, between the sleeve (15) and the bushing (17) and between the bushing (17) and the mounting base (11).
(FR) Une fibre optique (14) est accouplee optiquement a un element a action optique, une source lumineuse par exemple. De maniere a obtenir un accouplement optimum, la partie extreme de la fibre (14) est soigneusement ajustee par rapport a l"element (13) et ce, en trois dimensions. L"extremite de la fibre comporte un manchon (15) coulissant monte dans un manchonnage (17). Le manchonnage comporte une bride (18) ajustee contre la surface (12) d"une embase de montage (11) qui est perpendiculaire a l"axe du manchon (15). L"embase de montage (11) porte egalement l"element a action optique (13) pres de l"extremite de la fibre (14). Apres avoir ajuste le manchon (15) et le manchonnage (17) l"un a l"autre de maniere a obtenir un accouplement maximum entre la fibre et l"element optique, le manchon (15), le manchonnage (17) et l"embase de montage (11) sont fixes les uns aux autres en introduisant une colle extremement fluide a prise rapide, de preference un cyanoacrylate, entre le manchon (15) et le manchonnage (17) et entre le manchonnage (17) et l"embase de montage (11).
